A pivoting portion 1033 is located at each opposite end of the first link rod 1030 and a third pivoting portion 1034 is located between the first pivoting portion 1032 and the second pivoting portion 1033. Ru. First link rod 1030 is pivotally connected to positioning member 1010 by first pivot portion 1032 . First link rod 1030 is pivotally connected to second link rod 1031 by a second pivot portion 1033. The first link rod 1030 is pivotally connected to the side impact protection block 10 by a third pivot portion 1034. The end of the second link rod 1031 has a working portion 1035 remote from the first link rod 1030. The working part 1035 has a rib 1036 that projects towards the bottom wall of the side impact protection block 10. Via the rib 1036, the angle included between the deployment direction of the first link rod 1030 and the deployment direction of the second link rod 1031 is in the natural state. When the side impact protection block 10 needs to be folded from the deployed position to the folded position, the operating member 1035 of the second link rod 1031 is pulled along the direction indicated by the arrow F2 shown in FIG. The other end of the second link rod 1031 then drives the tip of the second pivoting portion 1033 of the first link rod 1030 to arch downward onto the rib 1036, thereby The front end of one link rod 1030 tilts upward onto the third pivot portion 1034 and drives the locating member 1010 out of the locating hole 21 and into the pivot socket 101 . The unlocking member 103 of this embodiment has the advantage of simple structure and convenient operation.

To facilitate the installation of the unlocking member 103, as shown in FIG. 9, the side impact protection block 10 includes an outer casing 104 and an inner casing 105 that are screwed together. The pivot socket 101 is arranged on the outer casing 104, and the pivot socket 101 is a hollow structure. The outer casing 104 has a storage recess 106 for storing the first link rod 1030 and the second link rod 1031. The storage recess 106 communicates with a hollow space within the pivot socket 101 . The side wall of the inner casing 105 has a pivot hole 108 for pivotally connecting the third pivot portion 1034 of the first link rod 1030. Furthermore, the inner casing 105 has a through hole 107 that communicates with the storage recess 106 . The working portion 1035 of the second link rod 1031 passes through the through hole 107 of the inner casing 105 and is exposed from the outside of the side impact protection block 10 .

The specific connection structure between the first link rod 1030 and the positioning member 1010 is preferably as shown in FIG. A hollow chamber 1016 is formed within the positioning member 1010. The side wall of the positioning member 1010 has a second longitudinal groove 1014 communicating with the hollow chamber 1016. The pivot axis of the side impact protection block 10 passes through the second longitudinal groove 1014 and the hollow chamber 1016. When the first link rod 1030 drives the positioning member 1010 to tilt upward, the positioning member 1010 moves upward along the pivot axis of the side impact protection block 10 through the second longitudinal groove 1014. . Moreover, a second elastic member 1015 may further be arranged within the hollow chamber 1016 of the positioning member 1010. The second resilient member 1015 provides a resilient force to drive the positioning member 1010 to automatically extend out of the pivot socket 101.

The operation of the safety seat base with the side impact protection linkage 100 of the present invention will be described below with reference to FIGS. 1-14.

When the safety seat base 200 does not need to be used, the side impact protection block 10 is folded into the storage recess 22 on the side wall 20. The locking portion 120 of the engagement member 12 extends out of the side wall 20 and engages into the engagement hole 1011 of the side impact protection block 10 to lock the side impact protection block 10 in the folded position. At this point, the positioning member 1010 is compressed by the side wall 20 and retracted into the pivot socket 101 of the side impact protection block 10, simultaneously compressing the second elastic member 1015.

When the seat body 300 is installed on the safety seat base 200, the bottom of the seat body 300 presses the protruding portion 140 disposed on the safety seat base 200, driving the driving member 14 to rotate. The drive member 14 pulls the engagement member 12 via the steel wire and the link member 13 to slide it along the direction indicated by the arrow F1 shown in FIG. 14, so that the locking portion 120 of the engagement member 12 It is separated from the engagement hole 1011 of the side impact protection block 10. At this point, the side impact protection block 10 is pushed out by the pressing force of the second torsion spring 102 and rotated from the folded position to the deployed position. Furthermore, the driving member 14 rotates to deform the elastic member 141, and at the same time the engagement member 12 rotates to deform the first torsion spring 122.

After the side impact protection block 10 rotates and escapes, the position of the positioning member 1010 of the side impact protection block 10 corresponds to the positioning hole 21 on the side wall 20 of the safety seat base 200. Since the positioning member 1010 is not pressed by the side wall 20, the positioning member 1010 escapes and engages into the engagement hole 21 by the action of the second elastic member 1015, so that the side impact protection block 10 It is held in the deployed position by positioning member 1010.

When the side impact protection block 10 needs to be folded, the working part 1035 of the second link rod 1031 is pulled to pull the positioning member 1010 out of the positioning hole 21 via the first link rod 1030. When the positioning member 1010 is disengaged from the positioning hole 21, the side impact protection block 10 can be pushed and rotated to the folded position. Then, the seat body 300 is removed. Since the protruding portion 140 of the driving member 14 is not pressed by the seat body 300, the driving member 14 rotates and returns due to the action of the elastic member 141. The tensile force on the steel wire no longer exists and the link member 13 returns under the action of the second torsion spring, whereby the engagement member 12 returns under the action of the first torsion spring 122. As a result, the locking portion 120 of the engagement member 12 enters the engagement hole 1011 of the pivot socket 101 to lock the side impact protection block 10.

Due to the innovative arrangement of the side impact protection linkage of the present invention, the safety seat base 200 has a side impact protection effect, and the linkage for controlling the side impact protection block 10 is optimized, thereby , the movement of the side impact protection block 10 is more sensitive, and the structure is simple and easy to manufacture.
